Note: The integrated SIM chip provides a mobile communications connection to a variety of
international service providers. In order to be able to utilise all functions of the device, you
must ensure that the device is located in the service area of one of these service providers.
You can find a list of all supported countries and associated service providers under
www.microtronics.at/footprint. A Managed Service contract with Microtronics Engineering
GmbH is required for use of the mobile data transmission (see
www.microtronics.at/managedservice). This includes the provisioning of the mobile
communications connection via the network of the service provider included in the above-
mentioned list.
4.8 General product information
The device is a compact, portable data logger for recording and transferring analogue and digital
signals. There are 4 universal inputs available, which can be operated in various analogue and
digital modes. The device operates without mains power and has a 14VDC voltage output to supply
the sensors. To save energy, the voltage output can be configured in such a way that it is only
activated just before and during a measurement. The myDatalog4 is also equipped with a battery
voltage output (3,6...4,1V ). The voltage at the battery voltage output is always available and can be
used to supply the switch contacts (e.g. relay) that are connected to one of the universal inputs. In
addition to the measurement data of the universal inputs, the internal "Battery", "GSM level" and
"Int. temp" measurement values are determined (see "Internal channels" on page 68). All of the
generated measurement data is temporarily saved on an internal data memory and is then wirelessly
transferred to a central location at a freely selected interval. The device is also configured via this
connection. The device is equipped with an integrated SIM card.
